Abstract

Background MicroRNAs (miRNAs) gene expression regulators are altered in psoriasis suggesting their role in the pathogenesis. Objective To study expression changes of inflammation and toll-like receptor (TLR)-related miRNAs, miRNA-155, let-7i, miRNA-21, miRNA-146a and miRNA-223 in peripheral mononuclear cells (PBMCs) and miRNA-21, miRNA-146a and miRNA-223 in plasma, from chronic plaque-type psoriasis patients who were treatment-naive or had undergone a washout period (n = 11). MiRNAs were evaluated at baseline and after 11 (9-12) months [median (25th-75th percentile range)] of methotrexate (MTX) or topical (betamethasone plus calcipotriene) treatment. Methods MiRNA expression was analysed with quantitative real-time reverse transcription-polymerase chain reaction. Matched controls were studied. Results Psoriasis patients presented, at baseline, increased expression of miRNA-155, let-7i, miRNA-146a, miRNA-21 and miRNA-223 in PBMCs, plus miRNA-21, miRNA-146a and miRNA-223 in plasma. Receiver-operator characteristic (ROC) curve analysis and area under the curve (AUC) showed that expression of these miRNAs have the potential to distinguish between psoriasis and controls. At baseline, miRNA-155 expression in PBMCs correlated with Psoriasis Area Severity Index (PASI) [12 (8-14)] (Spearman r: 0.7140, P < 0.05) suggesting a role in psoriasis. After MTX or topical treatment, reduction in PASI was observed [87.5% (75-100)]; miRNA-155 expression in PBMCs decreased; plasma miRNA-21, miRNA-146a and miRNA-223 were down-regulated. ROC analysis showed that miRNA-155 expression in PBMCs from psoriasis patients have the potential to distinguish between patients' samples at baseline and after treatment (AUC: 0.942, sensitivity: 0.91; specificity: 0.91 values; maximum likelihood ratio = 10). After treatment, miRNA-146a expression in PBMCs increased; miRNA-155/miRNA-146a ratio decreased, suggestive of a regulatory feedback; let-7i expression decreased; miRNA-21 and miRNA-223 remained ele

Abstract

On the occasion of the 70th annual meeting of the American Academy of Dermatology in San Diego the ILDS Executive Committee hosted a cocktail reception in the evening of 18 March. The reception, held at the Marriott Hotel on an evening of several competing attractions, was well attended by friends of the ILDS, who stopped by for a drink and a chat. Jean Bolognia and Chris Griffiths acted as official ILDS meeters and greeters for the guests. Our president, Wolfram Sterry gave a short speech of welcome and provided an update for those present on the recent achievements of and plans for the ILDS. The announcement of the Berlin summit was particularly well received by our member societies. Jerry Shapiro then took the floor to apprise us of the arrangements for the Vancouver World Congress, these too were greeted with enthusiasm...

Abstract

Background: Chronic inflammation plays an important role in the development of cardiovascular risk factors. Although the prevalence of comorbidities and cardiovascular events has been described in patients with psoriasis, few studies have examined subclinical atherosclerosis in psoriasis patients. Objective: Our objective was to investigate the prevalence of atheroma plaques in patients with severe psoriasis compared with control subjects and to analyze the association with metabolic syndrome, homocysteine levels and inflammatory parameters. Patients and Methods: This case-control study included 133 patients, 72 with psoriasis and 61 controls consecutively admitted to the outpatient clinic in Dermatology Departments (Granada, Spain.) Results: Carotid atheroma plaques were observed in 34.7% of the psoriatic patients versus 8.2% of the controls (p=0.001) and metabolic syndrome was diagnosed in 40.3% of the psoriatic patients versus 13.1% of the controls (p<0.001). Significantly higher mean values of insulin, aldosterone, homocysteine and acute phase parameters (fibrinogen, D-dimer, C reactive protein and erythrocyte sedimentation rate) were found in psoriatic patients. Binary logistic regression showed a strong association between psoriasis and atheroma plaque and metabolic syndrome after controlling for confounding variables. Limitations: The absence of longitudinal quantification of metabolic syndrome parameters and intima-media thickness in psoriatic patients. Conclusion: The chronic inflammation and hyper-homocysteinemia found in psoriatic patients may explain the association with atheroma plaque and metabolic syndrome. Cardiovascular screening by metabolic syndrome criteria assessment and carotid ultrasound in psoriasis may be useful to detect individuals at risk and start preventive treatment against the development of cardiovascular disease.
